What Are The Important Functions Of The Secondary Back Ridge Of The Timber Square Structure For Supporting The Formwork
May 28, 2022
In the traditional construction technology, the secondary back ridge in the formwork support system for buildings is a wood square structure. First of all, because it is a fixed size product and has a variety of building elevations, it must be cut off during the construction process, which is bound to cause waste. Moreover, the timbers can only be cut shorter and shorter, and can not be lengthened. If the buildings with large clearance elevation are encountered again, they can only be overlapped or new timbers can be purchased. If the lapping form is widely used, it will not only cause greater waste, but also cause quality problems (mold expansion, bulging, etc.). Secondly, because the traditional process is the combination of wood cube and steel pipe, and the material strength is different, the problem of mold running will occur due to the deformation of wood cube. Thirdly, as the concrete pouring is a wet operation process, the timbers will be deformed due to moisture, and the deformation will become larger with the increase of use times, resulting in the problem that the construction quality will become worse with the increase of floors during the construction process. In the end, the wood will change from straight to curved, from long to short, and from short to none because of continuous decay. In addition, large-scale use of wood products will have great fire hazards. In the new assembled formwork, the adjustable secondary back edge of the wall formwork is a steel product, which adopts the form of thin-walled C-shaped steel structure, with high strength and light weight. As the vertical edge of the formwork, it directly contacts the plastic building formwork. After the installation of the vertical wall formwork, stretch it to the required size, and directly vertically arrange it in parallel at a certain distance. Play the role of formwork supporting framework.
